We will have to make several trials for a precise adjustment but, as a reference, we recommend to give one and a half turns (360º + 180º) to the drag crank of the film for every picture. So, you should get normally between 29 and 32 pictures with a 36 pictures roll.

An easy way of seeing how the film passes and the amount of film that passes in every turn, is turning the crank hooked in the plate holder but without putting the cap of the camera. This is the way we will be able to see how the crank functions.

This trial can be made with an old or non-useful film roll.

The camera is made of three independent parts : body, cap and crank. This last crank is the only spare sold separate.
